STEAM-CONDENSER.

EPECIFICATIQN forming part of Letters Patent No. 357,401, dated February 8. 1857.

Application filed June 29, 1886. Serial NoIlOGfil-l. (No model.)

.To all whom it may concern:

Be it known that I, JOHN MOINTYRE, of the city, county, and State of New York, have invented a new and Improved SteanrOondehser, of which the following is a full, clear, and exact description.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.

Figure 1 is a longitudinal sectional elevation of my new and improved condenser. Fig. 2 is a transverse sectional elevation of the same on the line a: 00, Fig. 1. Fig. 3 is a longitudinal sectional elevation of a modified form of condenser, and Fig. 4. is a central transverse sectional elevation of the same.

The invention will first be described in connection with the drawings, and then pointed out in the claims.

A represents the casing of the condenser,

' which is cylindrical in form and closed at its ends by the tube-plates B B, which hold numerous annularly-disposed water pipes or tubes, 0, withinthe casing A. The tube-plate B (in the form of condenser shown in Figs. 1 and 2) is formed withv the central eductionport, D,'to which the air-pump is attached, and between the tube-plates B B is held the central tubular valve-casing, E, which is formed with the slots a and contains the sliding valve F, which is formed with the slots 1), corresponding with the slots a, and which is adapted to be moved longitudinally in the casing E by screw G, for opening or closing, more or less, the slots a in the casing E, to regulate the exhaust of vapors from among the pipes O to the eduction or exhaust port D. In the form shown in Figs. 1 and 2, between the tube-plates B B is also held the casing H, formed with numerous slots, 0. This casing 11 surrounds all of the tubes 0, is concentric with the casing A, and upon and surrounding it is the valve-cylinder I, formed with numerous slots, (1, to correspond with the slots aim the casing H, so that by turning the valve Ithe slots 0 may be opened or closed more or less, for the purpose of suddenly increasing or diminishing the immediate cooling-surface offered to the entering steam. The valve I may be turned by the worm-shaft J, located at the main induction-port K and meshing with the rack f,

formed upon or secured to the outer surface of the valve, as shown clearly in the drawings. The casing II and valve I are concentric with the outer main casing, A, and form in connection with it the surrounding steam-space L- In the form of condenser shown in Figs. 1 and 2 the space L entirely compasses the cooling-pipcs C, so that steam enters the cool space among the pipes from all directions and at every part of the condenser. Opposite the induction-port K (in the form of condenser shown in Figs. 1 and 2) is formed the pocket M for the water of condensation, and connected to this pocket is the pipe N, that is designed to connect with the air-pump for taking oft the liquid matter from the condenser, and in the pipe N is fitted the cock 0, so that by regulating this cook a small supply of water may be maintained at the bottom of the condenser, if desired.

In the form of condenser shown in Figs. 3 and 4 the steam-space L does not entirely surround thetubes G, the casing I being D-shaped in cross-section and supported upon the flat plate 1?, fitted in the casing A. Rising from the plate P is the hollow shell B, which conducts the vapors to the pocket M, formed by the plate I and outer casing, and also to the eXhaust-port,which, in this form of condenser, is central to the main casing A. The plate P is perforated at Z to permit the escape of the water that may condense and lodge upon the plate P, and I provide a valve, T, arranged to be operated by the handle t, for opening or closing, more or less, the aperture Z, so that a small supply of water may be maintained upon the upper surface of the plate I, if desired.

S S represent the condenser-heads covering the ends of the cooling-tubes.

By encompassing the cooling-tubes with a perforated plate and regulatingvalve a much greater and more equal distribution of the steam may be made over the whole coolingsurface than in condensers of ordinary construction, and the central perforate plate or casin g surrounded by the cooling-pipes enables the airpump to withdraw the uncondensed vapors equally from the whole length of the surrounding cooling-pipes, and so prevent the formation of air-pockets within the condenser among the pipes.

By means of the pipe N and valve 0 at the bottom of the condenser, which enables a supply of water to be kept at the bottom of the condenser, this water is reheated by the exhaust-steam, and acts as a cooling-surface by extracting heat from the exhaust-steam before itentersamongthecooling-pipes. Inthismannor the cooling effect is more instant and the temperature of the cooling parts more equal and the feed or condensed water much hotter (with the same degree of vacuum) than in ordinary forms of condensers, and in this circular form of condenser the steam comes in contact with the cooling-pipes from all sides, so that the maximum cooling effect is attained.

Having thus described my invention, What I claim as new, and desire to secure by Letters Patent, is-

1. 111 a surface steam-condenser, the cooling-pipes surrounded by a perforated or slotted casing and a regulating-valve to open or close the perforations or slots of the surrounding casing, substantially as described.

2. In a surface steam-condenser, a central perforated or slotted casing surrounded by the cooling-pipes and having a valve to open or close the slots or perforations in the casing, substantially as described.

3. The main casingA of the condenser, having the pipe N connected therewith and having the cock 0 fitted therein to maintain a supply of water at the bottom of the condenser, substantially as described.
